A DELETE statement is used to remove specified records from a table. It can also be used to remove all records.
DELETE FROM [ MEMORY ] table_name [ WHERE condition ]
DELETE deletes rows that satisfy the WHERE clause from the specified table. If the WHERE clause is absent, the effect is to delete all rows in the table. The result is a valid, but empty table.

table_name
The name of an existing table.
condition
An expression that returns a value of type boolean. Only rows for which this expression returns true will be deleted.
Example:
DELETE FROM developers WHERE name = 'Bob';
